Wordpress is what drives my blog and a few others I work with around the internet. It is worth mentioning that wordpress is a good blogging application. If you are considering getting into blogging consider the following:
1. It is simple to setup.
2. It is easy to use and manage.
3. It is easy to customize and many people freely share themes they have developed.
4. It does not require the user from knowing any code, while allowing advanced users to use code.
5. It is the easiest way to generate an RSS feed.
Before getting started, make sure your website is on a server you can install on. Many ISPs and Webhosts offer packages with a wordpress install ready to go.
